SPECIFICATION formingpart of Letters Patent No. 739,060, dated September 15, 1903. Application filed May 25, 1903. Seria1No.158,6Z9. (No modem To all whom it may concern.-

Be it known that I, ARTHUR CLARKE, a citizen of the United States, residing at Glenville, in the county of Cuyahoga and State of Ohio, have invented a certain newand useful Improvement in Spacing-Tables, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings.

This invention relates to spacing-tables for use in connection with various machine-tools, as punching-machines or drill-presses.

It consists particularly in an embodiment of features pertaining to the stopping of the table at predetermined points, whereby the holes to be punched in the work will be spaced regularly or according to a pattern previously laid out, and the necessity of individual measurement of each piece of stock will thus be obviated.

The invention may be here summarized as consisting, primarily, in the construction and combination of parts hereinafter set forth, reference being had to the accompanying drawings, specification, and claims.

Referring to the drawings, Figure 1 is a side elevation of my table, showing a piece of stock clamped thereon. Fig. 2 is an end elevation of the table, showing the supporting-tracks in cross-section. Fig. 3 is a vertical section on the line 3 3 of Fig. 2. Fig. 4 is a detail view of the stop-plate, showing the arrangement of the perforations therein in which the stops are mounted; and Fig. 5 is a cross-section of Fig. 4, showing the stops in place upon the plate.

Referring to the parts by letters, A A represent the tracks upon which the table is mounted. These tracks are shown as consisting of channel-beams connected together by suitable cross-braces A secured thereto by angle connections. Secured to the outer side of one of the channel-beams is an anglebar B. This angle-bar B has a projecting horizontal member or plate provided with holes. b for the purpose of receiving stops 1),

which have stems 1) extending down through said holes and receiving on their lower ends nuts 5* on the under side of the plate.

Mounted on suitable wheels 0, which operate upon the tracks A A, is the carriage O. This carriage is made of plates braced by suitable braces 0 Secured to the upper side of the braces C is abar D, which extends forward of the carriage, where it is provided with a clamping-jaw D for the purpose of securing the work Z to the carriage. This jaw is pressed toward the bar D by a bolt operated by a hand-wheel D said bolt passing into a nut on the under side of the bar D. A locking-pin d may be provided to pass through the bar D,'the. work Z, and the clam ping-plate D.

Brackets G are secured to the sides of the carriage and carry rollers G, which take on the under side of the top flanges of the rails A A for preventing the carriage from tilting up at therear.

Secured to one side of the carriage are two vertical angle-pieces c 0. These pieces a c are arranged so that they form a vertical guideway for a reciprocating stop-blade E.

This blade is provided with slots e, which cooperate with fixed pins c secured in the pieces '0 a, so that said blade may be free to be shifted up and down and into and out of the plane of the stops 1), carried by the plate portion B.

Pivoted in a bracket F on the carriage is a Weighted lever f, with a handle f projecting out over the side of the table, where it is connected by means of a link f to the stopblade E. A weight f adjustable upon this lever f near its other end, normally retains the blade in the uppermost position away fromthe plane of the stops b. g

It will be seen from the foregoing that when a piece of work Z is clamped in position between the clamping-plate D and the bar D and the carriage is moved along the tracks to feed the stock to the machine tool the carriage may be accurately stopped to hold the stock in the desired position by the operator drawing down on the lever f and causing the lower end of the blade E to abut against a properly-placed stop Z). These stops 1) may be arranged in the stop-plate B at any desired intervals, and the work will be punched according to the position of the stops.

In operating the device the lever is pulled down by hand until the stop-blade E projects into the plane of the stops and the carriage moved until said blade engages one of them. Then after the hole is punched when it is desired to pass to the next stop this lever is released and the carriage moved forward until the blade again after being depressed engages the next stop, and so on.

It will be noticed that there are several rows of holes b in the stop-plate B and that the holes of each row are staggered with reference to the holes of the other rows. This allows the placing of the pins 12 so as to stop the stock at any desired points as accurately as necessary. For example, with four rows of holes b successive holes in each row may have their centers an inch apart, while it will be possible to place a pin every quarter of an inch, and thus bring the stock within at least an eighth of an inch, one way or the other, of the desired position. More rows of holes would of course allow finer adjustment; but for many classes of work the four rows shown will give adjustment as accurate as necessary.

Having described my invention, I claim- 1. In aspacing-table, the combination with a traveling carriage, of means carried thereby for holding the stock, a stationary stop-plate provided with perforations, a stop adapted to occupy any of said perforations, a member carried by the carriage adapted to be brought into the plane of said stop, and means for moving such member into and out of said plane, substantially as described.

2. In a spacing-table, the combination of a base, a projecting perforated plate carried thereby, a stop adapted to occupy various of said perforations,a carriage mounted to travel on said base, and means mounted on the carriage and adapted to be moved into or out of the plane of said stop, substantially as described.

3. In a spacing-table, the combination with a traveling carriage, a stationary stop-plate provided with perforations, a stop adapted to occupy different ones of said perforations, a reciprocating member carried by the carriage, means for normally holding itoutof the plane of said stop, and means for moving it into such plane, substantially as described.

4. In a spacing-table, the combination with a traveling carriage, of a stationary stop-plate provided with perforations, stops arranged in said perforations, a reciprocating stop-blade carried by the carriage, a lever connected therewith and provided with means for normally holding said blade in elevated position,

and means for lowering the same into the plane of said stops, substantially as described. 5. In a spacing-table, the combination with a traveling carriage, a stop-plate provided wheels on said carriage adapted to rest on said base, a member carried by said carriage and adapted to cooperate with said stops, and means for moving said member, substantially as described.

7. In a spacing-table, the combination of a base, a horizontal projecting plate secured thereto, said plate having a plurality of holes through it, stops having shanks adapted to occupy said holes, a carriage mounted to travel on said base, a vertically-guided blade mounted on the carriage, and mechanism for moving said blade into or out of the plane of the stops, substantially as described.

8. In a spacing-table, the combination of a carriage, a pair of parallel flanges projecting therefrom, a pin extending from one flange to the other, a blade between said flanges and guided thereby and having a slot occupied by said pin, means for moving the blade, and a stop cooperating with it, substantially as described.

In a spacing-table, the combination of a pair of parallel angle-irons secured to said carriage, and having their flanges facing each other and forming a guideway, pins extending from one flange to the other, a stop-blade occupying said guideway and provided with slots cooperating with said pins whereby said stop-blade may be raised up and down, and means for thus reciprocating said blade, substantially as described.

10. In a spacing-table, the combination of a carriage, a pair of angle-irons secured to the carriage and having their flanges facing each other and thus forming a guideway, pins extending from one flange to the other, a blade occupying said guideway and provided'with slots cooperating with said pins, a weighted lever mounted on the carriage, a connection between the same and said blade, and a stop for cooperating with the blade, substantially as described.
